Which of these function has a greater rate of change than the function graphed bean why
1
3
12
.
12
Oya 2x + 12, because the rate of change of the graphed function is 9
y = 10x + 1, because the rate of change of the graphed function is 3
Oy10x 1, because the rate of change of the graphed function is 9
y = 212, because the rate of change of the graphed function in 3
Answer:
The 2nd option is correct.
i.e.
y = 10+1, because the rate of change of the graphed function is 3.
Step-by-step explanation:
From the graph,
Taking two points
(0, 0)(3, 9)Finding the rate of change or slope between (0, 0) and (3, 9)
Using the formula
Rate of change = Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [9 - 0] / [3 - 0]
= 9 / 1
= 3
Thus, the rate of change or slope of the line = m = 3
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the rate of change or slopeb is the y-interceptConsidering the function in 2nd option
y = 10x+1
Comparing with the slope-intercept form of the line equation y = mx+b
The rate of change or slope = m = 10
Conclusion:
The rate of change or slope of the graphed line: m = 3
The rate of change or slope of y = 10x+1 is: m = 10
Thus, the rate of change of y = 10x+1 i.e. m = 10 is greater than the rate of change of the graphed line i.e. m = 3.
Hence, the 2nd option is correct.
i.e.
y = 10+1, because the rate of change of the graphed function is 3.

It would Be C. Took longer then expected somehow.
If the measure of angle B is 67 degrees, what is the measure of angle C? Explain how you know
Answer:
If C is a supplementary angle (Adds to B to equal 180 degrees), then C=180-67=113 degrees.
If C is a complementary angle (Adds to B to equal 90 degrees), then C=90-67=23 degrees.

give the exact form and decimal form of the equation
8=9sin(6x)
simplify the equation into the form sin(ax)=b and use the inverse sin to solve for x
Answer:
Exact form: [tex]\sin{(6x)} = \frac{8}{9}[/tex]
Decimal form: [tex]\sin{(6x)} = 0.8889[/tex]
The solution for x is: The solution for x is of 10.455º
Step-by-step explanation:
We are given the following equation:
[tex]8 = 9\sin{(6x)}[/tex]
Placing into the desired format, the exact format is:
[tex]\sin{(6x)} = \frac{8}{9}[/tex]
In the decimal part, we divide 8 by 9. So
[tex]\sin{(6x)} = 0.8889[/tex]
Solving for x:
We apply the inverse sine. So
[tex]\sin^{-1}{\sin{(6x)}} = \sin^{-1}{0.8889}[/tex]
[tex]6x = 62.73[/tex]
[tex]x = \frac{62.73}{6}[/tex]
[tex]x = 10.455[/tex]
The solution for x is of 10.455º

32 students make up 100% of the class, what would the percentage be for 3 students
Answer:
Step-by-step explanation:
32=100%
3=3/32 x 100%
=300/32%
=9 3/8%
The percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.
What is percentage?A percentage, often known as percent, is a division by 100. Percentage, which means "per 100," designates a portion of a total sum.
Given:
32 students make up 100% of the class
Calculate the percentage of one student,
1 student = 100 / 32 = 3.125 %
Calculate the percentage of 3 students
3 students = 3.125 × 3 = 9.375%
Therefore, the percentage to be for 3 students if 32 students make up 100% of the class is 9.375%.

Complete the following sentence
If x is to 6 as 10 is to 15, then x is equal to .
Answer:
x=4
Step-by-step explanation:
x/6 = 10/15
x/6 = 2/3
3x=12
Answer:
x=4
Step-by-step explanation:
To find this, you must first figure out the relationship between 10 and 15. Since 10 is 2/3 of 15, "x" must be 2/3 of 6.
To find "x", divide 6 by 3 to get 2, then 2 by 2 to get 2/3 of 6 (4). Thus meaning X = 4.

An arithmetic sequence has a constant ratio 'r' and is defined by
[tex]a_n=a_1\cdot r^{n-1}[/tex]
computing the ratios of all the adjacent terms
[tex]\frac{16}{-4}=-4,\:\quad \frac{-64}{16}=-4,\:\quad \frac{256}{-64}=-4[/tex]
The ratio of all the adjacent terms is the same and equal to
[tex]r=-4[/tex]
Finding the next three terms
Given the sequence
-4, 16, -64, 256, …

A certain manufacturing procedure produces items that have a mean weight of 55 pounds and a standard deviation of 3.2 pounds. With what minimum probability can we assert that the weight of a randomly selected item produced by this procedure is between 45.4 pounds and 64.6 pounds
Answer:
99,7 %
Step-by-step explanation:
P [ 45,4 < X < 64,6 ] ???
P [ 45,4 < X < 64,6 ]
for X = 45,4
z₁ = ( X - μ₀ ) / σ
z₁ = 45,4 - 55 / 3,2
z₁ = - 9,6 / 3,2
z₁ = - 3
And fom z-table we find P [ X = 45,4 ] = 0,0013 or 0,13 %
z₂ = ( 64,6 - 55 )/ 3,2
z₂ = 3
And from z-table we find P [ X = 64,6 ] = 0,9987 or 99,87 %
Then
P [ 45,4 < X < 64,6 ] = 99,87 - 0,13 = 0,9974 or 99,74 %
Now if we look at the values:
μ₀ - 3*σ and μ₀ + 3*σ
we find 55 - 3*3,2 = 55 - 9,6 = 45,4 and 55 + 9,6 = 64,6
We know according to the empirical rule that values from μ₀ ± 3*σ will contains 99,7 % of all values

1. A piece of steel has a volume of 12 cm3
and a mass of 96g. What is its density?
Answer:
it's density is 8 g /cm³
Step-by-step explanation:
Mass (m) = 96 g
Volume (v) = 12 cm³
Density (d) =?
We know density is defined as mass per unit volume so
d = m/v
= 96 / 12
= 8 g/cm³
Hope it will help :)
